CONFIG_PRINTK_CALLER: Show caller information on printks

General informations

The Linux kernel configuration item CONFIG_PRINTK_CALLER:

Help text

Selecting this option causes printk() to add a caller "thread id" (if in task context) or a caller "processor id" (if not in task context) to every message.

This option is intended for environments where multiple threads concurrently call printk() for many times, for it is difficult to interpret without knowing where these lines (or sometimes individual line which was divided into multiple lines due to race) came from.

Since toggling after boot makes the code racy, currently there is no option to enable/disable at the kernel command line parameter or sysfs interface.
